Question

Prove :M<1 + m<2 +m<3=180
Given : ABC

Answer 1

To prove that M<1 + m<2 + m<3 = 180, we need to use the given information that ABC is a triangle.

In a triangle, the sum of the interior angles is always equal to 180 degrees.

Let's label the angles of triangle ABC as follows:

Angle A as M<1

Angle B as m<2

Angle C as m<3

Using the given information, we can rewrite the equation as:

M<1 + m<2 + m<3 = A + B + C = 180

This equation holds true because it is a fundamental property of triangles. Therefore, the statement is proven.
